Title: Information saving system in data processing device
Inventor: SAKAI SEIKI
IPC: G06F9/22
Filed: 1985-10-15
Abstract: PURPOSE:To save and preserve necessary memory contents, etc., without using a separately provided hardware by providing the first microprogram executing means to save information stored by the first switch means and the second microprogram executing means to initialize by the second switch means. CONSTITUTION:When the forcible interruption accompanying the information saving processing due to the setting of a flip-flop 13 is discriminated at the forcible interrupting processing microprogram, the information of a memory area 20 is saved to a saving area 22, a flip-flop 15 is set and lighted up. When a switch 11 is operated, it is inputted to a microprogram control part 18 as an initial signal and a flip-flop 14 is set. A microprogram control part 18 executes the initializing processing, recognizes that it is the initialization after the saving processing is executed, and executes the initialization of other part of a data processing device 1. Thus, the information of respective types of a register 21 and the information of an address 20 designated by an address switch 17 at the time of the forcible interruption are held while they are saved at an saving area 22.

IPC: H01L21/205
Filed: 1989-09-01
Abstract: PURPOSE:In a semiconductor device wherein a GaAs layer, on an Si substrate, and an insulating film, at its periphery, are formed and which makes the GaAs layer function as a functional element inclusive of the end part, to prevent the fall of functional element properties by insulating the end of the GaAs layer electrically from the end of an insulating film positioned at the periphery. CONSTITUTION:For a GaAs Hall element part 10, after GaAs is grown heteroepitaxially on an Si substrate 20 from which one part of an SiO2 film 34 is removed, mesa photoetching is done in the shape of a hole element. At this time, the Hall element is made about 10-50mum apart from the end face of the SiO2 film 34 as shown by marks 51 and 52. After that, a silicon nitride film 60 is accumulated by plasma CVD, and this is removed excluding necessary part. comparing this with the case where GaAs is grown to the end of the SiO2 film 34 and the GaAs Hall element is made as it is, in the case of the latter, from the inferiority of crystal property of GaAs at the end, the properties of the Hall element is inferior, and the Hall voltage falls to 80%, but in this case, such fall is not seen.

Abstract: PURPOSE:To manufacture Al alloy powder for forging having excellent fluidity and difficult-to-fly as dust without penetrating into gap of dies by crushing a formed body of raw material powder of the Al alloy and classifying to make the specific particle size distribution. CONSTITUTION:The raw material powder of Al alloy obtd. by rapidly cooling and solidifying with atomizing method, is formed with powder rolling device, etc. By this method, particles are once mechanically combined with each other. Successively, this formed body is crushed. The obtd. powder is classified by using a sieve to make the powder containing >=80mum the average particle diameter and <30% consists of <=44mum fine powder. By this method, the classified coursed particles and fine powder are returned back to the above forming process. The powder obtd. with this classifying process is annealed desirably at 150-<400 deg.C. By this method, the Al alloy powder for forging used for the forged body having excellent fluidity and little dispersion of tensile strength without deteriorating mechanical strength is obtd. Further, this powder has a little fear of burning the die by penetrating into gap between the dies and is difficult-to-fly as the dust and this is favorable to safety and sanitation.

Title: Wafer polishing adhesive
Inventor: YOSHIMOTO YASUBUMI
IPC: H01L21/304
Filed: 1990-08-31
Abstract: PURPOSE:To execute a peeling step at the ambient temperature and to reduce a malfunction generation ratio after cleaning by employing novolac type epoxy resin having a softening point in a special high temperature range and solvent as adhesive. CONSTITUTION:Novolac type epoxy resin used for adhesive for joining a wafer to a polishing plate in a wafer polishing step contains at least one epoxy group in one molecule, and 65-95 deg.C of a range of a softening point. The resin is dissolved in mixture solvent of ether solvent to be used as resin solution, the opposite surface to the surface to be polished of the wafer is coated therewith as adhesive solution, dried, and press-bonded in a state to be thermally fused on the plate. Here, since it does not contain curing agent, the resin is operated as thermoplastic resin, has higher softening point than that of the conventional bisphenol A type epoxy resin, and hence shows strong adhesive strength at the temperature at the time of polishing. Thus, the resin becomes low adherent substantially at the ambient temperature to be brittle, and is readily peeled.

Title: Garbage collection system
Inventor: KIMURA YASUNORI
IPC: G06F12/00
Filed: 1982-12-27
Abstract: PURPOSE:To increase efficiency of garbage collection and enable high speed processing by using the copying method which is favorable for variable length data and the trace and mark method which is advantageous for fixed length data. CONSTITUTION:Whole memory space is divided into a fixed length data domain and a variable length data domain, and the variable length data domain is further divided into two. The trace and mark method is used in the fixed length data domain and the copying method is used in the variable length data domain. When garbage collection is started in the variable length data domain, garbage collection is performed in the fixed length data domain even if the fixed length data domain is not started. Thus, as garbage collection by the copying method is limited in the variable data domain, processing of variable data can be performed efficiently and at high speed, and the fixed length data domain can be made wider and processing time can be shortened.

Title: Method and device for controlling voltage type power converter
Inventor: NAGASE HIROSHI
IPC: H02P27/06
Filed: 1983-12-05
Abstract: PURPOSE:To reduce a noise generated from a motor in a wide speed range irrespective of a load state by detecting the neutral point voltage of the motor and negatively feeding back a current command signal. CONSTITUTION:Sinusoidal voltage command signals v*, vv*, vw* of the outputs of current controllers 11U, 11V, 11W are added by an adder 16, and inputted to a neutral point voltage detector 17. The detector 17 outputs a neutral point voltage signal eN, which is negatively fed back to current command signals iu*, iv*, i* by adders 10U, 10V, 10W. Thus, since the harmonic waves contained in the signals vu*, vv*, vw* are eliminated, the noise level generated fom an AC motor 2 decreases to reduce the loss.

Abstract: PURPOSE:To ensure the stable control for switch between a using system and a waiting system by giving correction to the operation signal in case each deviation between operation signals delivered from a multiplex control system is kept higher than a set level for a set period of time. CONSTITUTION:Each of controllers 6-8 of a multiplex control system contains a deviation operator 3 and a PI operator 5.

The operation signals having intermediate values are selected among those operation signals 5a-5c and delivered 10a through an intermediate value selecting circuit 10. Furthermore a deviation comparator 11 and a timer 12 are added. The selected intermediate value signal 10a is compared with the operation signal 5a by a deviation comparator 11. If the signal 10a is higher than a set level, a deviation signal 11a is delivered to start the counting action of the timer 12. When the signal 11a lasts longer than the set period of time and energized, a timer signal 12a is delivered. Then the operator 5 gives correction to the calculated signal 5a with the signal 10a and delivers it.
